Applicants have discovered that error detection techniques, such as Forward Error Correction techniques, may be used to predict the degradation below a certain threshold of an ability to accurately convey information on a communication channel, for example, to predict a failure of the communication channel. In response, transmission and/or reception of information on the channel may be adapted, for example, to prevent the degradation below the threshold, e.g., prevent channel failure. Predicting the degradation may be based, at least in part, on data transmission error information corresponding to one or more blocks of information received on the channel and may include determining an error rate pattern over time. Based on these determinations, the degradation below the threshold may be predicted and the transmission and/or reception adapted. Adapting may include initiating use of a different error encoding scheme and/or using an additional communication channel to convey information.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method performed on a computing device that includes at least one processor and memory, the method comprising: predicting, by the computing device, a degradation of a communication over a first communication channel, where the predicting comprises comparing a number of data transmission errors with a threshold that indicates an ability of the first communication channel to accurately convey information; adapting, by the computing device in response to the predicting, the communication occurring over the first communication channel, where the adapting comprises at least one of: changing an error encoding scheme utilized for the communication occurring over the first communication channel, or performing the communication utilizing a second communication channel in addition to the first communication channel.
2. The method of claim 1 where the adapting comprises both the changing and the performing.
3. The method of claim 1 where a prediction resulting from the predicting is indicated by an adapt instruction.
4. The method of claim 1 , the method further comprising repeating the adapting in response to further predicting further degradation of the communication after the adapting.
5. The method of claim 1 where the predicting is based on-an error rate pattern of portions of the communication.
6. The method of claim 1 where the predicting indicates that the ability to accurately convey the information is anticipated to fall below the threshold.
7. The method of claim 6 where the threshold correlates to an acceptable level of performance for conveying the information over the at least one communication channel.
8. At least one computer storage media storing computer-executable instructions that, when executed by at least one processor of a computing device that includes memory, cause the computing device to perform actions comprising: predicting, by the computing device, a degradation of a communication over a first communication channel, where the predicting comprises comparing a number of data transmission errors with a threshold that indicates an ability of the first communication channel to accurately convey information; adapting, by the computing device in response to the predicting, the communication occurring over first communication channel, where the adapting comprises at least one of: changing an error encoding scheme utilized for the communication occurring over the first communication channel, or performing the communication utilizing a second communication channel in addition to the first communication channel.
9. The at least one computer storage media of claim 8 where the adapting comprises both the changing and the performing.
10. The at least one computer storage media of claim 8 where a prediction resulting from the predicting is indicated by an adapt instruction.
11. The at least one computer storage media of claim 8 , the actions further comprising repeating the adapting in response to further predicting further degradation of the communication after the adapting.
12. The at least one computer storage media of claim 8 where the predicting is based on error metrics of portions of the communication.
13. The at least one computer storage media of claim 8 where the predicting indicates that the ability to accurately convey the information is anticipated to fall below the threshold.
14. The at least one computer storage media of claim 13 where the threshold correlates to an acceptable level of performance for conveying the information over the at least one communication channel.
15. A system comprising a computing device and at least one software module that are together configured for performing actions, the computing device including at least one processor and memory, the actions comprising: predicting, by the computing device, a degradation of a communication over a first communication channel, where the predicting comprises comparing a number of data transmission errors with a threshold that indicates an ability of the first communication channel to accurately convey information; adapting, by the computing device in response to the predicting, the communication occurring over the first communication channel, where the adapting comprises at least one of: changing an error encoding scheme utilized for the communication occurring over the first communication channel, or performing the communication utilizing a second communication channel in addition to the first communication channel.
16. The system of claim 15 where the adapting comprises both the changing and the performing.
17. The system of claim 15 where a prediction resulting from the predicting is indicated by an adapt instruction.
18. The system of claim 15 , the actions further comprising repeating the adapting in response to further predicting further degradation of the communication after the adapting.
19. The system of claim 15 where the predicting is based on error metrics of portions of the communication.
20. The system of claim 15 where the predicting indicates that the ability to accurately convey the information is anticipated to fall below the threshold.
